For ressng the article the mold is in over downward and with the cavityof the press mold enlarged upward and being closed at its upper end by ablow head 33 through which air under pressure is admitted for pressingthe blank, as shown in Fig. 1.

fter the blank is pressed the mold is inverted to the position lshown inFig. 2 and the mold members separated as there shown, which will causethe blank 28 to be suspended from the lift-over 54. Then the liftover isslid from the position shown in Fig. 2 to that shown in Fig. 3 whichbrings the blank into the blow mold. The sections of the mold are thenbrought together and the lower end closed by the bottom 34 being movedupwardly into place in the lower end of the mold. Upon the introductionof air through the tube 30, the article will be blown to form the blankbottle 3G, as shown in Fig. Then the members of the mold are separatedleavingl the bottle suspended, as shown in Fig. 3, whereupon it isremoved.

The sections of the lift-over are held together by two springs 40, asshown in Figs. 7 and 8, which draw said sections together. The sectionsare separated by the separating movement of the members of the moldacting` through the anges 24'Iand 27 on the guides 23 and plates 26,respectively. The air tube 30 is supported on the portions 25 of thelift-over by an annular collar 45 which projects into the correspondingannular grooves 46 in the lift-over. The sections of the lift-over areseparated or pushed apart for the removal of the finished bottle by thespring 47 shown in Fig. 8, which lies under tension in half of the part25 of the lift-over. The spring 47 is weaker than the springs 40 and itsfunction is to separate the lift-over sections from the tube 30 afterthe lift-over sections have been separated from each other so as topermit the movement of the bottle, the neck of which is held betweensaid parts. After the bottle is removed the lift-over is slid back tothe press mold.'

As shown in Figs. 4, 5 and 6, the press mold members i7 and blow moldmember 117 aremade separatev from each other so as to leave a verticallyextending space be- `tween them, the upper ends being however 'securedtogether bythe guide 23 and lateral anges or centralportions 49 extendinand secured in and abutting against each ot er, as seen in Fig.- 4.AThis skeleton structure of the mold members is only for the purpose ofkeeping the mold members as cool as possible. Otherwise` the correspond-'ing halves of the press mold and blow mold could be in one solidpiece,but they are kept cooler by having the space between them shown in Fig.4, and are ri'dly secured togather by the means The invention claimedis:

1. A combined press and blow mold composed of two sections movableagainst and away from each other and having in their adjacent facescorresponding cavities for forming a press mold and, :l blow moldrespectively, a lift-over rn aber slidably mounted on one end of saidmold sections and with lateral flanges, and lguiding means secured tothe mold sections in which the edges of said lift-over member move andhaving flanges interlocking with the flanges on the lift-over so thatthe lift-over sections will not escape from the mold sections whenseparated.

2. A combined press and blow mold composed of two sections one of whichis mov able against and awav from the other so as to be always paralleland having oppositely located parallel guideways on their upper ends andhaving in their adjacent faces corresponding cavities for forming apress mold and a blow mold respectively, and a lift-over provided withlaterally extending portions projecting and operating in said guidewaysand interlocking therewith so that the lift-over sections cannot escapotherefrom from the mold sections when separated.

3. A combined press and blow mold composed of two parallel sectionsmovable against and away from each other and hav ing oppositely locatedparallel guideways on their ends and having` in their adjacent facescorresponding cavities for forming a press mold and a blow moldrespectively, anda semi-circular cavity at. lthe end of each of saidpress and blow molds, and a lift-over member having a central circularportion to lit in said circular cavities and plate-like eX- tensionsprojecting and operating in said guidewav's. said lift-over andguideways having interlocking fianges which prevent the lift-oversections from Aescaping from the mold sections when separated.

4. A combined press aniL blow mold cornposed of tvvo parallel sectionsmovable agairst and await from each other and having oppositely locatedparallel guideways on their ends' and having in their adjacent facescorrespondingr cavities torforming a press mold and a blow moldpecfively and a semi-circular cavity at lne end of each of said pressand blow molds` a liftover formed of two halves, each half having acentral semi-circular portion adapted to fit in the semi-circular cavityin the mold sections, a plate-like extension projecting into theguideways. and springs tending o hold the portions of said 1ift-overtogeth r.

5. In a. glass making machine, a frame having a pair of oppositelylocated guldes, a pair of transversely extending mold sections mountedvon .said guidesfrso that said mold sections may be slidably united andiso separated and having in their adjacent faces mold sections, sprintendin to hold the corresponding cavities for forming a press sectionstogether, an e spring ocated in one 10 mold and a blow moldrespectively, a, lift mold sectlon for pushing out the bott.TH overformed of sections slidably mounted therefrom when the other mold,sectiony is 5 `on one end of said mold sections which permoved awayfrom the bottle.

mits the mold sections to be moved against In witness whereof, I havehereuxltqV -or away from each other and whereby the aixed my signature.blank can be Atransferred from between the EDWARD S. BUTTON.
